The Toffees have conceded from corners in their last two outings – against Norwich City and Crystal Palace.

And, after Everton ended up drawing both of those matches, Martinez says that his side’s inability to defend from set pieces is costing them points.

"It is a problem at the moment," the Spanish boss said. "You shouldn’t concede from corners at that ratio. A corner cost us two points on Monday, and we conceded a corner and it cost us two points [against Norwich]."
